Cleaning Pro Keyboard USB/Graphite

I am in the process of tearing down the keyboard to clean it, especially the underside/bottom.

I have removed the four (4) screws from the back, the two (2) screws holding the USB cable @ the top front of the keyboard, the two (2) screws under the actual keys removed (left shift &amp; numeral six [6] from the right keypad) and the one (1) screw under the label on the top back side.

I am missing a screw to remove? Is there a screw under the Apple logo on the back?

Please do the google thing. There are a number of articles on the subject but it's hard to sort through all of them to figure out which apply to the M7803. One link was clearly marked as the 7803 but the site was 404.

The biggest headache with separating the top and bottom plastics is unsnapping the catches (tabs and slots) along the bottom leading edge of the keyboard. Apple's industrial designers went overboard incorporating invisible fasteners on its computer hardware. When the product is new, the plastics have greater flexibility for unsnapping, but after aging, the brittle nature of plastics becomes apparent. I partially separated a used Pro keyboard I bought, but didn't want to take the chance of breaking those catches. With the bottom housing tilted open as far as it would go, I slipped in a piece of cardboard wrapped with masking tape, to catch the pet hair that had gotten inside it. What was left was blown out with compressed air. The cleaning job wasn't as complete as I would have preferred, but I didn't want a loose joint from broken catches. Why couldn't they have used (3) mini-screws along the bottom edge, to tightly secure it together? Beyond that, it's a nice-looking keyboard. I've got four of them - two with the black keys, one with white keys, and one with ivory/light tan keys.

Next, remove two (2) screws from holder for USB cable from front and remove holder.

Next, remove the following key caps: left shift key, two (2) key caps to right of "L" key and two (2) key caps to right of numeral five (5) on numerical keypad. After removal of key caps, you will find three (3) more screws to remove. At this point, bottom adjuster will come free, retain pin holders for adjuster.

Next, on back under top label is a screw to be loosened. I could NOT get screw to come free, so I put a piece of tape over to retain screw. The back/bottom will come free and a metal shield for USB controller.

I rinsed all clear plastic with cool water. NO Soap Required! I used a small damp tooth brush for between key caps and outer edges. Removed key caps where rinsed.

If your keyboard is REALLY dirty, you can rinse complete keyboard. NO Soap, Period!

Let any washed/rinsed items COMPLETELY air dry.

If you are in a rush to reassemble keyboard, use PLENTY of compressed air and shake lose any H2O.

One final word, be ginger when handling keyboard, do NOT force anything apart or you break part(s). If you are NOT familiar with this tear down, I suggest you take your keyboard to some one with more experience with such item(s). This tear down should work with similar kind(s) of keyboard(s) (Model #: M7803).

Good luck and have some fun with this tear down.

It could encourage you to tackle other kinds of repair(s), fixes and DIY project(s)."
